Given numbers are 156, 486, 446, 257

The list of prime factors of all numbers are

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 446 are 2 x 223

Prime factors of 257 are 257

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 156, 486, 446, 257

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(156, 486) = 12636

GCD(156, 486) = ( 156 x 486 ) / 12636

= 156 / 486

= 156

Step2:

LCM(6, 446) = 1338

GCD(6, 446) = ( 6 x 446 ) / 1338

= 6 / 446

= 6

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 156, 486, 446, 257 is 1
